Abstract

Resilient polyurethane flexible foams of open cell structure are prepared by reacting a) polyisocyanates with b) a mixture containing 1. from 0.5 to 20 wt-% of a polyether comprising at least two hydroxyl groups having an oxyethylene group content greater than 50 wt-% and having an average molecular weight of from 400 to 10,000 and 2. from 99.5 to 80 wt-% of a compound produced by the addition of alkylene oxide to glycerol, optionally in mixture with ethylene glycol of an average molecular weight of from 400 to 10,000, and comprising a maximum of 20 wt-% oxyethylene groups, in the presence of c) water and optionally organic blowing agents, and d) catalysts, e) optionally, compounds having at least two hydrogen atoms capable of reacting with isocyanates, having molecular weights of from 32 to 399 and f) optionally, surface-active or flame-retardant additives and additional auxiliary substances, whereby the reaction is conducted in an index range of from 95 to 110.
